Is there any point of keeping this card open if it's not your main CC? I don't use this card at all, and unless I were buying a flight on AA, I can't seem to come up with a reason to keep the card...I got the bonus, and that's all I wanted. I guess the other benefit would be delaying the expiration of miles, but I'll probably use the miles before then. (Talking about the $750/4 mo. MC).
The perks on this card just aren't that great (to me).
